I am unable to update from the apple store
When I try to update from the apple store, I get a message that says "cannot verify a secure connection with the App Store" or it times out.
MacBook Pro (13-inch, Mid 2012)
Take each of the following steps that you haven't already tried until the issue is resolved. Back up all data before making any changes.
Step 1
Check the status of the Mac App Store. If the store is down, wait tor it to come back up. There may be a localized outage, even if the status indicator is green.
Step 2
Check that the date (including the year) and time shown by your system clock are correct.
Step 3
Restart your router and broadband device, if different.
Step 4
If you connect to the Internet through an HTTPS or SOCKS proxy server, follow the instructions in this support article, or deselect the proxy entirely.
Step 5
Boot in safe mode and try again.
Step 6
Make sure Parental Controls aren't active for your account.
Step 7
Follow the instructions in this support article to change your DNS settings.
Step 8
Launch the Keychain Access application. From the menu bar, select
Keychain Access ▹ Preferences ▹ Certificates
There are three menus in the window. Change the selection in the top two to Best attempt, and in the bottom one to CRL. Log out, log back in, and test.
Step 9
If possible, test on a different network, such as a public Wi-Fi hotspot or the cellular network of your phone.
Step 10
If you've moved to a different country, select
Store ▹ View My Account
from the App Store menu bar, then click
Change Country or Region
and update your billing information.
